the application of these elements to the bottle. y

In carrying out the invention, there is provided a frame 1, supporting atable 2. Supported for rotation upon the frame 1, are spaced shafts 3and 4, extended transversely of the table, each shaft being providedwith a drum 5, the conveyer 6 being passed about the drums.

Supported by the table 2, and disposed upon either side of the conveyerbelt 6, are folders 7, the forward ends 8 of which upstand from thetable. To the rear of the portions 8, the folders are carried towardeach other so as to overhang the table, as denoted by the numeral 10 inFig.6. The rear portions 9 of the folders are disposed relatively closeto the table, as compared with the intermediate portions, as acomparison of Figs. 6 and 7 will show. Referring particularly to Fig.3,it will be seen that the edges of the folders converge as they extendrearwardly, as denoted by the numeral 12.

Brackets 14 are supported upon the table 2, these brackets projectingforwardly, and supporting an idle roller 15, disposed in close relationto the conveyer belt 6. Bearing brackets 16 are mounted upon the table 2to the rear of the idle roller 15, the brackets 16 carrying forrotation, a shaft 17, equipped with a roller 18, disposed to the rear ofthe idle roller 15 and positioned in close relation to the conveyer belt6, adjacent the longitudinal center of the belt. To the rear of thebearing brackets 16, other bearings 19 are disposed upon the table 2,the bearings 19 carrying for rotation, a secondary shaft 20, which, asshown to best advantage in Fig. 4, may be spring pressed, as at 21,toward the table 2. The shaft 20 carries spaced rollers 22, cooperatingwith the rollers 23 (Fig. 5) secured to a secondary shaft 24, mountedfor rotation upon the table 2, below the shaft 20. The secondary shafts20 and 24 may be operatively connected at one end, by means of steppinions 25. The rollers 22 are formed, upon their adjacent ends, withpulleys 26, about which belts 27 are passed, the belts 27 being carrieddownwardly over idle secondary pulleys 28, carried by a shaft 29,rotatable in framesupported bearings 30. The belts 27 are passed overpulleys 31, carried by a primary shaft 32, supported for rotation uponframe-carried brackets 33, the belts 27 being carried upwardly from thepulleys 31, over primary pulleys 34, mounted upon a shaft supported forrotation in bearings 36, supported by frai'ne-carried brackets 37. Thebelts 27 consist, each, of a horizontally disposed segment, and avertically disposed segment, as will be understood readily from theforegoing description.

A face plate 38, uprightly disposed and acting as a guide for the foldedmaterial, is secured to the frame 1, below the pulleys 31.

Secured to the shaft 32, for rotation therewith, are spacer wheels 39,the arms 40 of which are disposed out of alinement with each other,longitudinally of the shaft 32.

Supported by the frame 1, below the face plate 38, and, if desired,adjustably held upon the frame 1, is a hopper 41, projectingreaii'wardly from the frame. Disposed within the hopper 41, is a presserfoot 42, to which is secured a longitudinally adjustable, forwardlyextended arm 43, united with a strap 44, surrounding an eccentric 45,carried by a shaft 46, held for rotation in frame-supported bearingbrackets 47 Disposed in the hopper 41 and slidable therein, is anupright-head block 100, (see Fig. 1), provided with a lateral foot 101for its sup aort. Secured to the shaft 46, is a pulley 48, about whichis passed a belt 49, the belt being carried upwardly about a pulley 50secured to the shaft 4. The shaft 3 is equipped at one end, with apulley 51, about which is passed a belt 52, operatively con nected withthe armature shaft 53 of the electric motor 54, supported upon the frame1, or disposed in close relation thereto. The shaft 3 likewise carries apulley 55, about which is passed a belt 56, engaging a pulley 57 uponthe shaft 17 The shaft 4 is operatively connected with the shaft 24, bymeans of a belt 58.

Before describing specifically, the operation of the machine, it will bepointed out what manner of material the device is adapted peculiarly tohandle. WVith this end in view, Figs. 8, 9, 10 may be examinedprofitably.

In wrapping bottles and the like, a board 59 ordinarily fashioned fromcorrugated flexible material, has applied to one face thereof, a stripof paper 60, the ends (31 of which protrude beyond the ends of the board59, as indicated in Fig. 8. Glue is applied to the lower face of theboard 59, adjacent one end thereof, whereupon the lateral edges 61 ofthe strip 60 are folded over the lateral edges 62 of the board 59 asindicated at 63 in Fig. 9. The lateral edges of the strip 60 are finallyflattened down upon the upper face of the board, as shown at 64 in Fig.10. The board 59 and the strip 60 are then wound transversely around thebottle to form a tube. The board 59 and the strip 60 being properlyglued, manually or otherwise, the board and the strip are laid upon thetable 2 and advanced upon the conveyer belt 6, the parts of the materialbeing sub stantially in the positions shown in Fig. 8. The conveyer belt6 will advance the material until the ends 61, passing along theconverging edges 12 of the folders '7, are disposed substantially asshown at 63 in Fig. 9, rear portions 9 of the folders finally foldingover the lateral edges of the strip into the positions indicated by thenumeral 64. The material, passing beneath the idle pulley 15, will beengaged by the roller 18, the roller 18 cooperating with the beltconveyer 6 in advancing the material from the forward end of the machinetoward the rear end thereof. The conveyor belt 6 will feed the materialbetween the rollers 22 and 23, the folding of the ends of the strip 60being thus consummated. The material, with the ends of the strip 60folded upon the board 59, as in Fig. 10, will pass beneath the belts 27,the belts carrying the material over the idle rollers 28, and passingthe material downwardly along the outer face of the plate 38, into thehopper 41, whereupon the presser foot 42 will advance the materialtoward the head block 100 which will recede as the material accumulatesin the hopper. The rotary spacers 39 strike the upper edge of eachwrapper after it has been deposited in the hopper 41 and flip the upperedge of the wrapper rearwardly, out of the way of the next wrapperdescending along the plate 38 into the hopper 41.

The operation of the device, so far as the drives are concerned, is asfollowsz-lVhen the motor is in operation, the armature shaft 53 thereof,through the instrumentality of the belt 52, will rotate the shaft 3,causing the conveyer belt 6 to advance the material beneath the folders7. The shaft 3, by means of the belt 56, will rotate the shaft 17,causing the roller 18 to cooperate with the conveyer belt 6 in advancingthe material. The shaft 4, rotating under the action of the beltconveyor 6, will, through the instrumentality of the belt 58, cause arotation of the shaft 24, the shaft 24 through the step pinions 25causing a rotation of the shaft 20, the rollers 22 and 23 thuscooperating to crease the strip 60 down upon the board 59. The shaft 20in its rotation will actuate the belts 27, whereby the material iscarried downwardly into the hopper 41. The shaft 4, actuating the belt49, will impart rotation to the shaft 46, actuating the eccentric 45 andcausing a reciprocation of the arm 43, whereby the presser foot 42 willbe advanced and retracted in the hopper 41. After the glue has beenapplied to the board 59 and the strip 60, these elements, being fedthrough the machine, will emerge therefrom in position to be wrappedabout the bottle, the ends of the strip 60 being automatically foldedover and around the ends of the board 59.

In fashioning manually, wrappings of the character hereinbeforedescribed, the major portion of the time of the operator has beenconsumed in bringing the ends of the strip 60 around the ends of theboard 59, and in pressing the ends of the strip upon the board.

The machine herein disclosed requires merely that the glue be applied tothe elements of the wrapping, and that these elements be properlypositioned with respect to each other, before the wrapping, in glued,but unfolded condition, is placed upon the table 2 for advancement bythe conveyer belt 6.
